1 John 2:17-19

New Revised Standard Version Catholic Edition

¹⁷ And the world and its desire^[a] are passing away, but those who do the will of God live forever.

Warning against Antichrists

¹⁸ Children, it is the last hour! As you have heard that antichrist is coming, so now many antichrists have come. From this we know that it is the last hour. ¹⁹ They went out from us, but they did not belong to us; for if they had belonged to us, they would have remained with us. But by going out they made it plain that none of them belongs to us.
